Abstract

Upon attempting to display information consisting of large amounts of data on a display portion of a portable terminal, there existed a problem that long durations of time were required for completion of the display, and display capacities were insufficient. A search signal is sent from a portable information equipment to a server, and the server conducts a search on a database based on the search signal and sends information of the search to a display device such as a television or projector mounted at a place where an unspecified number of the general public are present such as a large-sized monitor in a hotel lobby, in a train station meeting room, or out on the street.

Description

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a system for delivering a broad range of information including letters or characters, symbols, images, voice and the like.
2. Description of the Related Art
Systems have been developed for members of an information-providing network to use portable information equipment to receive information. As an example of this kind of services, a member of the service accesses a server using the portable information equipment via a communication line, and performs a procedure for obtaining selected information. Then, the server searches a database for information in accordance with the request of the service member, and sends the information to the portable information instrument via the line, with the result that the information displayed on a display portion of the portable information equipment can be obtained.
For example, a service member wanting to know what time a movie X starts connects to the server from the portable information equipment through a communication line, and inputs the signal (URL, search key words, etc.) used to obtain the selected information, and transmits the signal to the server. The server searches the database based on the signal, and sends the results to the portable information equipment. Thus, the service member was able to obtain letter or character information and information in the form of a still image as large as could be displayed on the display portion of the portable information equipment, for example, “movie title: XX, movie theater: YY, show time: ZZ”.
However, according to the conventional method for displaying information on a display portion of a portable information equipment, the information could not be more than what could be displayed on a small display screen of the portable information equipment. Therefore, there was a limit to the amount of data (information) that the service member could obtain. For example, the service member was not able to obtain information by displaying a moving image on a display portion of a large such as a television.
Further, in the case when the display portion of the portable information equipment was used to try to obtain information with a large amount of data, there were problems in that a long duration of time was required to complete the display, the display power was insufficient, and information storage unit included in the portable information equipment had insufficient capacity so that all of the information could not be received.

 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1
By referring to FIG. 1, description will be made of a method using a portable information equipment A as means for performing a procedure to display information on a display device C disposed where an unspecified number of the general public are present (for example, a waiting room of a train station or an airport). FIG. 2 shows the structure of the present invention.
First, an access is established through a telephone number for requesting a provision of information to a server B from the portable information equipment A. Commonly known method for providing the information (for example, DialQ2 by NTT) may be used for procedures up to the point where the portable information equipment A receives the provision of information from the server B. When a user accesses the telephone number for information provision, the server B then indicates that the information provision will be charged. If a user continues to stay connected as he or she is, it is considered that consent has been given for the charge, and the information provision is performed.
Note that, however, in addition to the instance in which the user has knowledge about the information provision system (the telephone number for receiving information provision, etc.) before using the system, it is also possible to conceive of an instance in which a user uses the information provision system without any preliminary knowledge about the system at all.
Therefore, in order to increase the number of peoples using the information provision system, a special telephone number and method of use may be displayed on the display portion when electromagnetic waves sent from the portable information equipment A are sensed, or means for performing a call through a voice from a voice output portion may be provided to the display device. Accordingly, a greater number of people may take interest in the information provision system.
In order for the display device C to be individually identifiable when the server B transmits information, an ID number (number, symbol or name) distinguishable from other display devices is applied to the display device C. On the other hand, entity identification of the portable information equipment A can be performed based on, for example, the telephone number. As shown in FIGS. 1 and 2, in order for the server B to receive the information provision from the portable information equipment A, server B transmits a signal for individually identifying the portable information equipment A and for individually identifying the display device C (FIG. 1 portable information equipment A (1)).
Note, however, that in addition to performing entity identification of the display device C by directly inputting the ID number into the portable information equipment A and transmitting it to the server B, it is also possible to provide means for the display device C to send a known individually identifiable sound signal such as those used by Fax machines. In this case, the sound signal sent from the voice output portion is picked up at the portable information equipment A and notified to the server B, to perform the entity identification of the display device C.
Also, it is possible for the portable information equipment A and the display device C to an individually identifiable information exchange through electromagnetic waves such as light and infrared rays and by indicating the result of the exchange to the server B, to perform the entity identification of the display device C.
The display device C has a unit for detecting electromagnetic waves sent from the portable information equipment. The system is configured such that the response of the display device C detecting the electromagnetic waves sent from the portable information equipment A is transmitted to the server B. In this way, the information which needs to be verified in order to perform the information provision is sent to the server B from the portable information equipment A and from the display device C (FIG. 1 server B (1)).
It is also possible to configure the method so that the server B displays some numeral and letter or information on the display device C and the user inputs and transmits the same numeral that was displayed on the screen or inputs a response to information obtained from the display. In this way, the system can verify that the person who wants to have information displayed on the display device C is actually in a position where the information displayed on the display device C can be viewed.
Once the server B verifies the requirements for searching for and transmitting information, it then transmits information on an information provision menu screen to the display device C (FIG. 1 server B (2)). The display device C displays the menu (FIG. 1 display device C (2)) thereon, and transmits the search signal from the portable information equipment to the server B (FIG. 1 PORTABLE INFORMATION EQUIPMENT A (2)(3)).
Based on the search signal, the server B conducts a search on the database and transmits information produced by the search to the display device C (FIG. 1 server B (3)). The display device C then displays the transmitted information (Fig. DISPLAY DEVICE C (3)(4)).
When it is desirable to obtain more detailed or specific information than the information displayed on the display device C, a search signal is transmitted from the portable information equipment A to the server B (FIG. 1 Portable information equipment A (4)(5)).
The search signal can be transmitted continuously from the portable information equipment A to the server B until the selected information is displayed, and the information can be displayed on the display device C.
Note that, however, communication with other different servers (such as a second server, a third server, ad infinitum) is possible, as shown in FIG. 2. If information matching the search signal is not found by a search at server B, then the search signal transmitted from the portable information equipment A can be transmitted to the second server which is different from the server B. In this case, the search is conducted at a database managed by the second server. Information can then be transmitted to the display device C from the second server via the server B.
The server B applies a charge in exchange for performing the provision of information. Methods for applying the charge can include such various methods as: (1) known charging methods (such as obtaining consent in advance before applying the charge by providing information, such as is used in DialQ2 service of NTT); (2) configuring the system so that everything before the menu screen is conducted free of charge, and then the charge is applied once the information provision has begun on the basis of the amount of information provided or on the basis of the duration of time or number of pages required to provide the information; and (3) once the provision of all of the information has been completed, the party receiving the information determines the value of the information and pays accordingly.
The server B may use a party D (for example, NTT) that manages communication lines in order to apply the charge to the portable information equipment A.
Embodiment 2
Description will be made of a method for a server B to receive a search signal from a portable information equipment A, to conduct a search on a database, and to display information on a display device C through a line capable of delivering information with large amounts of data (for example, optical fibers, and high-speed data transmission line such as wiring for transmission for digital broadcast). Note that, in this embodiment, a portable telephone is used as the portable information instrument A.
As shown in FIG. 5, a set top box 302 for processing information sent from the server B is provided to the display device C.
For example, in the case where information regarding professional baseball/team xx is desired, a user connects to the server B through a special telephone number for information provision. Verification is performed on a display portion 103 of a portable telephone as shown in FIG. 3, while a push button (input means) 104 is used for inputting. The result is that an entity identification code assigned to the display device C which the user wants to output the information is transmitted.
In the server B shown in FIG. 4, a control means 201 performs entity identification of the portable telephone A and entity identification of the display device C according to a signal of the portable telephone A which has accessed to a special telephone number. When verification has been made, information is transmitted so that a menu screen is displayed on a display portion 303 of the display device C.
While looking at the menu screen displayed on the display portion 303 of the display device C, the user uses the push button 104 of the portable telephone A to input and send the search signal to the server B such that the information regarding professional baseball/team xx is transmitted.
Having received the search signal, the server B conducts the search on the database 202 and sends the information regarding professional baseball/team xx to the display device C. The display device C processes the information transmitted through the set top box 302 and displays the information in the display portion 303.
Note that, however, information transmission from the server B to the display device C is complete upon display of the information on the display device C.
From the information regarding professional baseball/team xx displayed on the display device C, it is also possible to transmit a search signal further specifying the information, for example, the information regarding professional baseball/team xx/player yy, to the server.
Transmission of the search signal from the portable information equipment A is repeated to produce the result that detailed information saved in the database regarding professional baseball/team xx/player xx is displayed on the display portion 303 of the display device C.
Further, it is also possible to configure the method so that the portable telephone A can be used to change the image display conditions of the display device C (brightness, contrast, and tone) and the input language settings. In this way, the information is displayed according to user's own preferred screen display style and in the user's competent language.
There is a possibility of a problem occurring in the case where the information is not displayed accurately in the display portion 303 of the display device C, and yet the charge is applied even though the information has not been provided. In order to prevent this type of situation, it is desirable to create rules in advance such as: in the case that the information has not been displayed on the display device C, an information stating that the information has not been displayed is transmitted from the portable information equipment A to the server B via a known means such as electronic mail. In this case, the server B sends the information again.
The server applies the charge in the case that the information provision was carried out without an error. There are various imaginable methods for applying the charge, as shown in the first embodiment.
Note that, however, in the case that there are a plurality of requests for information provision, a sequence for carrying out the information provision is mediated by the server B, and then the information provision is carried out.
Embodiment 3
In the case where only normal telephone lines are connected to the display device, time is required until the information sent from the server is displayed on the display device C. Therefore, as an example of sending and receiving the information, it is possible to use a communication satellite in a supplementary fashion for sending and receiving the information by radio.
The search signal is sent from the portable information equipment A to the server B, and the server B conducts the search on a database 202.
From multiple sets of information of the search on the database 202, information consisting of small amounts of data is sent to the display device C using telephone lines. Information consisting of large amounts of data is sent from the server B to the display device C using the communication satellite.
Information sent through either method is processed by the set top box 302 connected to the display device C and displayed on the display portion 303 of the display device C. In order to obtain more specific information, a search signal is sent from the portable information equipment A to the server B and the search is repeated, with the result that the information is displayed on the display portion 303 of the display device C.
In this embodiment, a communication satellite was used as means for supplementing sending of the information, however, it is possible to use a transmission relay means other than the communication satellite.
Embodiment 4
It is possible to configure the method so that information for commercial advertising of profit-making activities for broadly informing people of merchandise and services (referred to throughout this specification as commercial advertising) and advertising by non-profit organizations relating to morality, welfare, etc. (referred to throughout this specification as public service announcements) can be sent from the server B to the display device C when a search signal is sent from the portable information equipment for a predetermined period of time. This information provision system can be used for utilizing the display device C as an advertising medium.
For example, a person wanting to publicize his or her own store (hereinafter, referred to as a publicity client) enters a contract with the server B to use the information providing system of the present invention for publicity. The contract indicates, for example, that the information providing system is used in order to display publicity information stored (accumulated) on the server B on the display device C at periods of time when many people will view the display device C (high publicity effect time periods). The publicity client can be charged for “storing information for publicity activities” and for “displaying advertisements (information)”. Also, the fees can be adjusted according to the period of time during which the information is displayed. Since the information to be displayed on the display device C is stored in the server B in advance, there is no need for the publicity client to request for information display from the portable information equipment. In this way, the system can be used effectively even when not being used as the information providing system (i.e., times when a search signal is not sent).
Additionally, in the case when there are multiple requests to display information (publicity), the system can be configured so that the server B mediates and performs the publicity activities of the multiple publicity clients in sequence.
Embodiment 5
It is also possible to register the entity identification ID number, etc. of a display device C mounted on means for carrying and transporting people or on means for transportation (for example, bus, taxi, train, boat, etc.) and to send the information from the server B to be displayed on the display portion 303.
In order to display the information on the display portion 303 of the display device C, it is sufficient that the portable information equipment A is used as an input terminal and the search signal is sent to the server B. It is sufficient if the server B conducts the search on the database 202, sends the information of the search to the display device C, and displays the information on the display portion 303 of the display device.
It is possible to use the display device C shown in this embodiment as the information providing system cited in Embodiments 1 to 4 of the invention, or as a publicity medium for displaying publicity information.
Embodiment 6
The portable information equipment A sends electromagnetic waves at times other than when communicating. A method for undertaking publicity activities of the information providing system itself using a display device C having means for detecting the electromagnetic waves sent by the portable information equipment A is explained.
The display device C can be configured to display an explanatory overview of the information provision system (how information can be received, what kinds of information can be received, etc.) or to send a call from the voice output portion, etc when the above-mentioned electromagnetic waves sent by the portable display device A are detected.
Information for explaining the information providing system can be stored on the server B, then sent to the display device C and displayed. The information may also be stored in the set top box 302 mounted on the display device C.
In this way, the display device C can be used as a publicity medium for increasing usage of the information providing system of the present invention, and for conducting publicity activities for the information providing system itself.
Embodiment 7
The display portion of the display device C is large and when the display device C is used to display only a single piece of information, a large portion of the display is wasted. Therefore, the system can be used to conduct multiple flows of information provision simultaneously (i.e., procedures of sending the search signal from the portable information equipment A, and the server B conducting the search on the database). In this case, multiple sets of information are sent from the server B to the display device C, the display portion of the display device C is divided into multiple regions, and the different multiple sets of information sent from the server B are displayed simultaneously.
Also, it is possible to display multiple sets of information sent from the server B in an overlapping fashion in the display portion.
Note that, however, it is possible to use any of Embodiments 1 to 6 in combination with the present embodiment.
Embodiment 8
At specified times, the server B does not send the information of the search in the database based on the search signal sent from the portable information equipment A to the display device C but may designate a specific broadcasting company and configure the system so as to display information delivered by this news agency, newspaper company or broadcasting company as it is. Also, the signal for displaying the delivered information does not have to be sent from the server B to the display device C. Further, the signal for displaying the delivered information from the server B does not have to be sent to the display device C, and the set top box mounted on the display device C may be set to display the delivered information.
Note that, it is not only possible to display the delivered information at pre-programmed times but also to display the information sent out from the broadcasting company as it is by the server B operating the system (i.e., send a signal). The broadcasting company can be a private-sector broadcasting company (also referred to as a commercial broadcasting company) or a public broadcasting agency, and the delivered information can be the content that is generally delivered. It is possible to display delivered information including news regarding current events delivered by news agencies and newspaper companies.
By combining this embodiment with Embodiment 7, it becomes possible to display information produced in response to the search signal simultaneously with the display of the broadcast.
Note that, this embodiment can be used in combination with any of Embodiments 1 to 7.
The information providing system according to the present invention enables a search signal to be sent from a portable information equipment to a server, with the result that the server conducts a search for information, the information is sent from the server to a display device located where an unspecified number of the general public may be present, and the information is displayed on the display device having strong display capacities.
In contrast to the case in which the information is displayed on a small display screen of the portable information equipment, there no limitation on the size of the display screen. Furthermore, the display capacity of the image may be strengthened and more precise image information can be obtained on a large screen without making the user wait for a long time.
Additionally, it is not necessary to display information consisting of large amounts of data on the display portion of the portable information equipment. Therefore, reduction of electricity consumption is encouraged, and the portable information equipment itself can be made smaller and lighter in weight to the extent the size of its power source becomes smaller.
Also, by using the portable information equipment, identification of the individual user of the information providing system becomes possible. Therefore, the supplier of the information provision can easily charge the individual using the information providing system, and the user of the information providing system can obtain information just as though he or she were manipulating a television by remote control in his or her own room.
